At least 11 people, including Afghan forces, have been killed in a bomb explosion outside a US military base in Afghanistan’s eastern province of Khost, officials say.

District governor Amir Badshah Dawran said a bomber detonated his explosives after he walked up to a checkpoint in Ali Sher district along the Pakistan border in Khost province on Saturday.

He added that four more police officers and another civilian ( Munafiq / hypocrite , agent of intelligence agency , intelligence official , undercover police officer in civilian dress etc ) have also sustained injury in the attack.

Dawran blamed the attack on the Taliban Mujahideen. However, no group or individual has claimed responsibility for the attack.
